WebThe First Law of Thermodynamics states that energy can neither be created nor destroyed, only transferred or transformed from one form to another. The Second Law of Thermodynamics states that whenever energy is transferred or transformed, some of it is wasted as heat, making it unavailable for further use. Webperpetual motion, the action of a device that, once set in motion, would continue in motion forever, with no additional energy required to maintain it. Such devices are impossible on grounds stated by the first and second … Web(second law) to identify whether a process can occur or not. Fig. 1: Heat transfer from a hot container to the cold surroundings is possible; however, the reveres process (although satisfying the first law) is impossible. A process can occur when and only when it satisfies both the first and the second laws of thermodynamics. prompt analysis examples
